Water curtain paint spraying machine

Abstract

The invention relates to accessories of paint spraying machines and provides a water curtain paint spraying machine. The water curtain paint spraying machine comprises a water curtain cabinet; the water curtain cabinet comprises a cabinet body, an axial-flow induced draft fan, a water suction pump, a plurality of fine atomization nozzles, a multi-stage water curtain board, an activated carbon adsorption mechanism, a water-steam separation mechanism and a hollow ball filtering layer; the hollow ball filtering layer is detachably installed at the position, above an upper partition plate of the multi-stage water curtain board, of an exhaust channel inside the cabinet body; the water-steam separation mechanism is detachably installed at the position, above the hollow ball filtering layer, of the exhaust channel inside the cabinet body; the activated carbon adsorption mechanism is arranged at the position, above the water-steam separation mechanism, of the exhaust channel inside the cabinetbody; and the axial-flow induced draft fan is arranged at the position, above the activated carbon adsorption mechanism, of the exhaust channel inside the cabinet body. The problems that a water curtain board of an existing paint spraying machine causes a too large water curtain, and consequently water spots splash, the quality of a painted product is decreased and the painting mist treatment effect is poor are solved.

Description

technical field [0001] The invention relates to a paint spraying machine, in particular to a water curtain paint spraying machine. Background technique [0002] The water curtain spraying machine is composed of a chassis, a water tank, a water curtain plate, a water circulation system, and an air filtration system. It can effectively prevent the discharge of waste paint and pollute the environment when the workpiece is sprayed normally. The basic process of the water curtain spraying machine to deal with the paint mist is: under the action of the exhaust fan gravity, the air containing the paint mist flows towards the inner wall water curtain plate of the water curtain spraying machine, and a part of the paint mist directly contacts the water on the water curtain plate Part of the paint mist is washed away by the water curtain when it passes through the water curtain falling down from the water curtain plate, and the remaining paint mist that is not captured by the water fil...

AI Technical Summary

Problems solved by technology

In the existing water curtain cabinet, the water in the water tank is pumped to the top of the water curtain plate through the water circulation system, and flows down along the water curtain plate to form a water curtain. However, when the water curtain formed on the water curtain plate is too large, it will cause splashes. The splashed water will splash on the painted parts, affecting the quality of the painting. At the same time, the paint mist in the water curtain cabinet cannot be effectively absorbed and removed, and the unit structure used for paint mist absorption and removal in the water curtain cabinet is inconvenient to clean and maintain
